I noticed the other day that the WoW Background Downloader started for 3.2. MMO Champion is reporting on it. Check out their site here for more information, but something I wanted to point out is what MMO Champion has been discussing for a while now. This is about the special Trading Card mounts. Here's what they are reporting:

TCG Mounts Changes
As I posted earlier this week, it seems that the Trading Card Mounts Bind on Pickup Removal is intended, all the spells used by the server to "create" the mounts in the player inventory have been changed and now point to new items.

This is probably to end all the scams going on with these mounts. I guess you will just get one mount for each code now, and will be able to use it or sell it at the auction house if you want to.
